The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
As the race in space was winding down, soviet scientists turned inwards. You'd never guess that this is the site of one of their great achievements. This hard-to-find rusty cap in the ruins of a ...
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
It's not the deepest hole ever drilled, but it is the deepest sample of this kind of ocean rock researchers have ever obtained, Lang said.. Lang and the team were after the type of rock that once ...
The Xiaozhai Tiankeng has been well known to local people since ancient times. Xiaozhai is the name of an abandoned village nearby and means "little village", and "Tiankeng" means Heavenly Pit, a unique regional name for sinkholes in China.
The only part of the Earth that turns out to be hollow is a gigantic geode, and soon after the drill moves through it, the hole it created fills with magma. The 1986 animated television show Inhumanoids featured regular visits to the Inner Core in most of its 13 episodes. Each of the three villainous creatures theoretically ruled over certain ...
Indeed, while TBJH was initially discovered in 2021, scientists only measured its depth down to 900 feet due to limitations in the echo-sounder technology — which calculates speed based on sound ...
Drilling holes does not provide direct evidence against the hypothesis. The deepest hole drilled to date is the Kola Superdeep Borehole, [60] with a true vertical drill-depth of around 12 km (7.5 mi). However, the distance to the center of the Earth is nearly 6,400 km (4,000 mi). [61]
